Hello, installed a CentOS 6.5 x86_64 vm from iso (create VM and then run once connecting CD iso).
System reboot several times and power on from web admin gui and all seems ok.
At a certain point I upload guest-tools iso to my engine for future windows VMs. Taken ovirt-guest-tools-3.5_5.iso and try to mount it
In engine the downloaded file seems ok and I can loop mount it for test. [root@ovirtmgr ~]# mount -o loop ovirt-guest-tools-3.5_5.iso /media [root@ovirtmgr ~]# ll /media total 19382 dr-xr-xr-x. 4 root root 2048 Jul 7 13:21 bin dr-xr-xr-x. 4 root root 2048 Jul 6 17:25 drivers -r--r--r--. 1 root root 19839504 Jul 17 12:49 ovirt-guest-tools-setup.exe -r--r--r--. 1 root root 88 Jul 7 13:18 version.txt -r--r--r--. 1 root root 2266 Jul 2 16:40 win-driver-license.txt [root@ovirtmgr ~]# umount /media

Also the uploaded file seems ok [root@ovirtmgr ovirt-engine]# md5sum /var/lib/exports/iso/3b23161a-18a3-4cfa-bc78-f4fe2052b19e/images/11111111-1111-1111-1111-111111111111/ovirt-guest-tools-3.5_5.iso ad98fc5db09183acd1620b5effb5e151 /var/lib/exports/iso/3b23161a-18a3-4cfa-bc78-f4fe2052b19e/images/11111111-1111-1111-1111-111111111111/ovirt-guest-tools-3.5_5.iso
If I try to connect cd to the running VM from web admin portal I get a window with the error:
Error while executing action Change CD: Internal Engine Error

do you see the call for changeCD in vdsm? it looks like the call somehow failed does it happens all the time?
The Vm runs with this command line generated by oVirt

It seems to be a general problem. Tried also to mount the iso of CentOS 6.5 that I used to install the VM itself but I get the same error.
Donna if it is somehow related also with what I previously wrote about cd and install in 3.5 rc2; see http://lists.ovirt.org/pipermail/users/2014-September/027465.html
